Effect of Postoperative Kinesio Taping on Knee Edema, Pain, and Range of Motion After Total Knee Arthroplasty and Anterior Cruciate Ligament Reconstruction: A Systematic Review and Meta-analysis of Randomized Clinical Trials.

BACKGROUND: Kinesio taping (KT) has been shown to be clinically effective in a wide range of musculoskeletal disorders. Despite evidence supporting KT, there still needs to be more certainty regarding its clinical worthiness in managing postoperative conditions. This study aims to assess the effect of postoperative KT on knee edema, pain, and range of motion (ROM) when added to routine physiotherapy after knee surgery.

METHODS: In this systematic review and meta-analysis, MEDLINE, Embase, Scopus, Web of Science, and CENTRAL databases were searched from their inception to July 2023. Randomized controlled trials (RCTs) comparing routine physiotherapy with and without KT were included. Random-effect models were used to calculate the standardized mean difference (SMD), confidence interval, and heterogeneity (I2).

RESULTS: Sixteen RCTs on 842 operated knees were included. KT reduced knee edema in first week (SMD, -0.59, p < 0.001), 14th postoperative day (POD) (SMD, -0.78, p < 0.001), and 28 to 42 days postop (SMD, -0.66, p < 0.001). The KT demonstrated significant pain improvement in second week (SMD, -0.87, p < 0.001) and the fourth week (SMD, -0.53, p < 0.001). The KT groups demonstrated ROM improvement within second week (SMD, 0.69, p = 0.010) and in the 28th POD (SMD, 0.89, p = 0.009). Subgroup analysis demonstrated minimal heterogeneity in anterior cruciate ligament reconstruction (ACLR) cases. However, it did not show significant superiority regarding ankle, calf, or thigh edema and Lysholm scale.

CONCLUSION: This study suggests that adding KT to routine postoperative physiotherapy reduces pain and knee edema after total knee arthroplasty or ACLR. Low to very low certainty of evidence for all outcomes and the limited number of studies emphasize the need for more high-quality primary studies to explore the optimal method of KT application and its effectiveness in specific knee surgeries.
